SK9867Y1 - Axle of an all-terrain vehicle with electric drive - Google Patents

Abstract

Axle of the electric off-road vehicle consists of the central module (1), which is made of light carbon material in the form of a shell structure filled with honeycomb. On the front and back of the central module (1) there are holes (2) for connecting a connecting module, for example a rotary joint for the purpose of connecting several axle modules into one unit, which creates the possibility of creating a vehicle with two axles and four-wheel drive, or by connecting the axle modules directly through the holes (2) and creating a wheel-slip steered vehicle. In the central module (1) there is a battery box with electric accumulators (3), control electronics (4) with a remote signal receiver for driving the vehicle and frequency converters (5) for controlling the rotation speed of the wheel electric motors (11). The power electronics of the central module can be cooled using radial fans (6). Semi-axles consisting of a fixed plate (7) with linear guides (8) and a movable plate (9) with linear bearings (10) are attached to the central module (1) on both sides. Part of the moving plate is a wheel electric motor (11) with a brake disc (12), an electrically controlled brake caliper (13) and a wheel (14). Springing and damping of the semi-axle is provided by a system of two spring-dampers (15). By connecting two axles using an electromechanically controlled joint, it is possible to create a modular arrangement of a vehicle with a 4x4 drive powered and controlled by electrical energy stored in batteries that are part of the axle.

Description

The technical solution relates to the construction of a two-wheel axle module for the modular construction of a joint or slip-controlled vehicle, which can be created from several axle modules and thus create a vehicle with a drive, e.g. 4 x 4, 6 x 6, 8 x 8. The technical solution falls into the field of mechanical engineering, specifically in the field of construction of land vehicles.

Current state of the art

- In the construction of articulated vehicles, the front axle is different from the rear, and both axles are driven by a central energy source, i.e. an internal combustion engine, which is located in the vehicle body either above the front or rear axle.

- The axles are constructed as rigid axles, where the wheels are driven by drive shafts or hydraulic power transmission is used.

- The wheels that are part of the axle are usually not sprung.

- Axles are usually made of steel or cast iron components.

- Axles are not interchangeable.

The essence of the technical solution

The aforementioned shortcomings of the prior art are extended by the construction of the axle of the electric vehicle, where the central module is made of light composite materials based on carbon fibers, on which the semi-axles mounted on linear lines and suspended by a system of spring shock absorbers are attached. The central module also contains an energy source, i.e. a battery box. The battery box with batteries is used to power the control electronics with a remote signal receiver and frequency converters to control the rotation speed of the wheel electric motors, which are part of the wheel. It also serves to power the electrically controlled brake caliper, which ensures vehicle braking. By connecting two axles using an electromechanically controlled joint, it is possible to create a modular arrangement of a vehicle with a 4 x 4 drive powered and controlled by electric energy stored in battery boxes, or by directly connecting several axles without an electromechanically controlled joint to create a slip-controlled vehicle.

Implementation examples

The axle of an all-terrain vehicle with an electric drive consists of a central module 1, which is made of carbon material, inside which there is a battery box 3 with electric batteries, control electronics 4 with a remote signal receiver and frequency converters 5 for controlling the speed of the vehicle and cooling fans 6. On the front and back of the central module there are 2 holes for connecting a connecting module, for example a swivel joint for the purpose of connecting several axle modules into one unit, which creates the possibility of creating a vehicle with two axles and four-wheel drive or by connecting axle modules directly through the holes 2 and create a wheel-slip steered vehicle. A semi-axle is attached to the central module 1, which consists of a fixed plate 7 with linear guides 8, to which a movable plate 9 is connected by means of linear bearings 10, while a wheel electric motor 11 with a wheel 14, a brake disc 12 and electrically controlled brake caliper 13, while the system of two shock absorbers 15, the upper end of which is connected to the fixed plate 7 of the half-axle and the lower end to the movable plate 9 of the half-axle, is intended for damping and suspension of the axle. By joining the axles, a vehicle with the same axles can be created, and this vehicle can be steered with a joint or wheel slip.

Industrial applicability

Electric off-road vehicle axles can be used in the construction of all-wheel drive vehicles 10 powered by electricity. By connecting at least two axle modules, it is possible to create a vehicle steered by slippage or by means of a steered coupling joint and to create a joint steered vehicle.
